Seems under specs

I’m not deploying it to go through trees. I even have a tower with 4 sectors of 3.65 plus a 900 MHz FSK panel pointed toward an area with those pesky green things because I don’t expect the 3.65 to go there unless it’s a short link with maybe a tree or two in the middle somewhere, same as I would do with 2.4 GHz. I view 3.65 as spectrum not fouled by consumer devices or FHSS, and so far the only WISP we can see is using Ubiquiti so if we stay in the upper 25 MHz we should not bump heads with them. And the prospect of an additional 100 MHz of spectrum in the future is a plus. Even though it is not licensed exclusive use, you don’t have interference from every Tom, Dick and Harry. I am viewing it kind of like a replacement for 2.4 GHz with the possibility of getting access to 3550-3650 in the future. So should we assume that when people say they are not getting much distance in 3.65 with bare SMs, it is not a comment on the 450 product per se, but the lack of magical foliage penetrating power? Also, it would help to know if people are using the Cambium sectors, third party sectors, or omnis. I have a couple dual pol omnis in 5 GHz and the distance is unimpressive, I don’t think I’d try an omni in 3.65 especially if I was trying to go through trees and not use a dish, that’s 3 strikes against you. Maybe 4 strikes if you consider no WIMAX/LTE super sauce. I really wish people would loosen their grip on the concept that the main reason to consider PMP450 in 3.65 GHz is for NLOS. Even if that works for you, it’s way too narrow a view of the product.

Or are you talking about through trees? I have not been impressed with performance through trees, even with a dish. But I’m not happy with –80 and 4X, I don’t want to eat up all the capacity on such an expensive piece of gear with just a few subs. And I don’t want customers calling every time the leaves get wet or covered with snow. At some point I think we’ll see something similar to the Force100 but for now it’s a dish or a connectorized SM with a panel. When I asked about a Stinger/CLIP type of product, I was told the size at 2.4 or 3.65 GHz get too big or else the gain isn’t worth it.

Are you using a dish with most, or is there a stinger available or something "mid-term" ? Must be honest, we haven't tried the dish yet. Need to very soon as fall is basically here... ----- Original Message ----- From:David Milholen via Af<mailto:af@afmug.com> To: af@afmug.com<mailto:af@afmug.com> Sent: Sunday, September 21, 2014 11:34 AM Subject: Re: [AFMUG] Dear Cambium Chris, We are rockin 3.65 450 AB channels replacing 90% of our 900 subs. Migration is taking time due to cap X. I took down our first 900AP which was our first aP900 installed last week.

We have no alternative to 900 for most of our customers where we are, too many hills and trees. We are still deploying 900 MHz radios in large quantities simply because we can't use anything else. Sure would be nice to have an easy way to configure those radios, we (Animal Farm) have only been asking for that feature for the last 8 years, not like they didn't know about it or have the time to figure it out. Now they are giving it to us, but only on a platform where we don't really need it yet. While I understand that PMP100 is somewhat antiquated, Cambium is still making money on it and will continue to make money on it, so why not give us at least some development beyond bug fixes at least until there is a 900 replacement? Why not a 450 in 900 MHz that's using the newer hardware but still only 2x modulation. We would literally buy thousands of them within the next year. -- <Davidmvcf.jpg>
